	Oligopoly Watch
		Whatever the upshot (and I belive that some of theose craft brewers will come to regret their confidence), it's another example of oligopolies adapting to the innovations of others by copying them and confusing the market and watering-down (double meaning intended) the competition.
		We have often noted that big, industry-leading companies are often poor at generating major innovations, ones that are not simply an improvement on an existing product or technology but rather one that has the potential to disrupt an industry.
		Oligopolies grow to have influence over public policy t their profit.

	Oligopoly Prices 1
		The oligopoly firms will compete on price so that the price and profits will be the same as those of a P-competitive industry.
		The oligopoly price and profits will be somewhere between the monopoly and competitive ends of the scale.
		Oligopoly prices and profits are "indeterminate." That is, they may be anything within the range, and are unpredictable.

		Oligopoly theory makes heavy use of game theory to model the behaviour of oligopolies: Game theory is often described as a branch of applied mathematics and economics that studies situations where players choose different actions in an attempt to maximize their returns.
		An oligopoly may be categorized as either a homogeneous oligopoly or a differentiated oligopoly.
		Oligopoly equilibrium occurs where the oligopoly firm is able to balance the output effect and the price effect.

	Oligopoly
		An oligopoly may be categorized as either a homogeneous oligopoly or a differentiated oligopoly.
		In a competitive market situation that is not an oligopoly, firms compete by acting for themselves to maximize profits without regard to the reactions of their competitors.
		While smaller firms may operate at the fringes of an oligopoly without affecting the other firms in the industry, the actions of a major firm in the oligopoly typically cause reactions in the other firms in the industry.

		This guarantees that oligopolies in the US will have to find a Nash equilibrium (as discussed in the first two sections of this study guide, rather than a collusive equilibrium that may be better for both firms, but worse for other firms and consumers.

		An oligopoly is market form in which a market is dominated by a small number of sellers (oligopolists).
		Oligopoly exists when there are a small number of firms selling in a single market.
		The usual reason for this situation is that the optimal size of firm, the size at which average cost is minimized, is so large that there is only room for a few such firms; this corresponds to the sort of cost curves shown on Figure 10-10b.

		The two "real options" boundary conditions at the common threshold level X*(Q) are sufficient for the optimal strategic exercise of the option due to his Proposition 2 (the myopic firm threshold is equal to the firm's strategic threshold).
		Grenadier's section 5 shows that, besides the monopoly and perfectly competitive industry cases, it is also possible to solve the oligopoly case as a single agent optimization problem.
		As mentioned in the introduction, this is a very important result because permits the extension of known (or easier to obtain) results in perfectly competitive setting to the oligopoly case.

	Price Theory, Chapter 11: Game Theory, Strategic Behavior, and Oligopoly
		When it fails to do so, as in the analysis of oligopoly or bilateral monopoly, it rapidly degenerates from a coherent theory to a set of educated guesses.
		A second problem is that, for reasons that will be discussed in Chapter 19, it may often be in the interest of the government doing the regulation to support the producers against their customers rather than the other way around.
		We will try to find the Nash equilibrium for an oligopoly first on the assumption that a firm's strategy is defined by the quantity it produces and then on the assumption that it is defined by the price the firm charges.

		The implication of this is that firms in oligopoly are interdependent.
		Many economists believe that the main form of competition in oligopoly is non-price competition, and advertising in particular, to highlight the differences in the products.
		Although it is assumed that firms aim to maximise their profits in the kinked demand curve model of oligopoly (see later), it is quite possible that the managers of these firms may have other managerial objectives, associated with power of sales maximisation (if their salaries are based on sales).
